This is a sawed and polished specimen for microprobe analysis by the late Bart Cannon. Cannon had his own microprobe in his basement. This specimen show a 3mm highly reflective metallic grain of Pekoite. Silvery Galenobismutite needles can be seen around the Pekoite. I do not have the analytical papers, but comes with a Bart Cannon label and a note on the Cook label stating "probed". See Cannon label in prov. tab.
